Question

A shopkeeper mixes $80kg$ sugar worth of $Rs.6.75$ per $kg$ with $120kg$ of sugar worth of $Rs.8$ per $kg$. He earns a profit of $20\%$ by selling the mixture. He sells it at the rate of

• A. $Rs.7.50$ per $kg$
• B. $9$ per $kg$
• C. $Rs.8.20$ per $kg$
• D. $8.85$ per $kg$

Answer 1

The correct option is B $9$ per $kg$

Total cost $=80\times 6.75+120\times 8=Rs.1500$
Total selling price $=1500+(1500\times \frac{20}{100})=Rs.1800$
$S.P.$ per $kg=\frac{1800}{200}=Rs.9$
Hence, option $B$ is the correct answer.
